Dietes
''Dietes'' is a genus of rhizomatous plants of the family Iridaceae, first described as a genus in 1866. Common names include wood iris, fortnight lily, African iris, Japanese iris and butterfly iris, each of which may be used differently in different regions for one or more of the six species within the genus. Most species are native to southern and central Africa, with one ('' Dietes robinsoniana'') native to Lord Howe Island off the coast of Australia. A few species have become naturalized in other parts of the world. Taxonomy These plants were formerly placed in the genus ''Moraea'', but were reclassified because they are rhizomatous. Like ''Moraea'', they differ from ''Iris'' in having flowers with six free tepals that are not joined into a tube at their bases. Some references mention the species ''Dietes vegeta'' or ''D. vegeta variegata'', springing from some confusion with ''Moraea vegata'' (which grows from a corm, not a rhizome). The name ''D. vegeta'' is commonly mis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dietes Robinsoniana
''Dietes robinsoniana'', the Lord Howe wedding lily, is found naturally only on Lord Howe Island. It grows on cliff faces, often in exposed situations. Found also on forest margins and the tops of Mount Gower and Mount Lidgbird and behind the beaches on Lord Howe Island. It is one of the world's most intriguing and remarkable biogeographic disjunctions, with its nearest phylogenetic relatives occurring in Africa.

Dietes Bicolor
''Dietes bicolor'', the African iris, fortnight lily or yellow wild iris, is a clump-forming rhizomatous perennial plant with long sword-like evergreen pale green leaves, growing from multiple fans at the base of the clump. This species belongs to the iris family Iridaceae. It can form large clumps if left undisturbed for years. It is commonly cultivated in its native South Africa, where it is often used in public gardens, beautification of commercial premises and along roadsides. It is also cultivated in mild temperate In geography, the temperate climates of Earth occur in the middle latitudes (23.5° to 66.5° N/S of Equator), which span between the tropics and the polar regions of Earth.

Dietes Grandiflora
''Dietes grandiflora'', the large wild iris, African iris or fairy iris, is a rhizomatous perennial plant of the family Iridaceae with long, rigid, sword-like green leaves. This species is common in horticulture in its native South Africa, where it is often used in public gardens, beautification of commercial premises and along roadsides. The blooms are white marked with yellow and violet. Dark markings are found at the base of the outer tepals. These are borne in abundance during summer, especially after rain. These flowers will last a couple of days and are then followed by 5 cm long green capsules that contain very dark brown seeds, dispersed when the capsule splits open. Cultivation Plants prefer dappled shade to full sun where they will flower in profusion, though they will grow in shaded areas (with an accompanying loss of flower production). Under favourable conditions, the clumps multiply rapidly. ''Dietes grandiflora'' are drought and frost hardy, making them popula ...

Dietes Iridioides
''Dietes iridioides'', commonly named African iris, fortnight lily, and morea iris, is a species of plant in the family Iridaceae that is native to Southern Africa. Description This species has sarmentous stems with branches bearing lily- like flowers 6-8 cm (2.3-3.1in) wide, white with yellow central markings. Growing up to 60cm (24in) in height and 30-60cm (12-24in) in spread, it forms dense basal tufts in the shape of an extended fan. Its preferred habitat is in semi-shade under tall, open trees. It has white flowers marked with yellow and violet, with six free tepals that are not joined into a tube at their bases. These flowers last only for a few days. The seedpods of the plant often bend the stalks down to the ground where they have a better chance of propagating a new generation of plants. Distribution ''Dietes iridoides'' is widely distributed in Africa, from Ethiopia to South Africa. Taxonomy These plants were formerly placed in the genus ''Moraea'', but were recl ...

Lord Howe Island
Lord Howe Island (; formerly Lord Howe's Island) is an irregularly crescent-shaped volcanic remnant in the Tasman Sea between Australia and New Zealand, part of the Australian state of New South Wales. It lies directly east of mainland Port Macquarie, northeast of Sydney, and about southwest of Norfolk Island. It is about long and between wide with an area of , though just of that comprise the low-lying developed part of the island. Along the west coast is a sandy semi-enclosed sheltered coral reef lagoon. Most of the population lives in the north, while the south is dominated by forested hills rising to the highest point on the island, Mount Gower (). The Lord Howe Island Group comprises 28 islands, islets, and rocks. Apart from Lord Howe Island itself, the most notable of these is the volcanic and uninhabited Ball's Pyramid about to the southeast of Howe. To the north lies a cluster of seven small uninhabited islands called the Admiralty Group. The first repo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iridaceae Genera
Iridaceae is a family of plants in order Asparagales, taking its name from the Iris (plant), irises, meaning rainbow, referring to its many colours. There are 66 accepted genera with a total of c. 2244 species worldwide (Christenhusz & Byng 2016). It includes a number of other well known cultivated plants, such as freesias, gladioli and crocuses. Members of this family are perennial plants, with a bulb, corm or rhizome. The plants grow erect, and have leaves that are generally grass-like, with a sharp central fold. Some examples of members of this family are the blue flag and yellow flag. Name and history The family name is based on the genus ''Iris (plant), Iris'', the largest and best known genus in Europe. This genus dates from 1753, when it was coined by Swedish botanist, Carl Linnaeus. Its name derives from the Greek goddess, Iris, who carried messages from Mount Olympus, Olympus to earth along a rainbow, whose colours were seen by Linnaeus in the multi-hued petals of many ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afric ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and hav ...
